两种范式下有意遗忘的实验研究

本文以英语词汇为材料,采用自由回忆和再认测验作为外显记忆测验,词干补笔测验作为内隐记忆测验,探讨小学五年级学生在单字范式与字表范式下的有意遗忘效应及其机制。结果发现:(1)单字范式下,三种测验中都存在有意遗忘效应;而字表范式下,只有词干补笔和自由回忆测验中存在有意遗忘效应;(2)三种测验中,单字范式下记忆项与遗忘项的差异显著高于字表范式下二者的差异。这表明,两种范式下有意遗忘效应产生的机制是不一致的,且相较于字表范式,单字范式下有意遗忘效应更显著。     

Estrogen and Neural Plasticity

Converging clinical evidence suggests that postmenopausal estrogen therapy in women is associated with improved cognition and a reduced incidence of Alzheimer's disease. In experimental work, investigators have found estrogen to promote changes in synaptic plasticity within the nervous system. In this article, we review both the clinical and the experimental literature, and consider mechanisms of action of estrogen on neurons and synaptic plasticity, and how they might protect against the cognitive impairments of old age.

从神经可塑性的视角看压力与疾病的关系

压力致病是一个复杂的过程,涉及到与多种致病因素的相互作用、多个器官系统的激活和反馈、不同发育阶段对疾病的易感性等。这个过程中,神经可塑性起着重要的调节作用。本文以神经可塑性为切入点,阐述了压力、发育阶段、个人发展、疾病发生之间的关系。     

Neural Plasticity and Human Development

In this article, I argue that experience-induced changes in the brain may be a useful way of viewing the course of human development. Work from the neurosciences supports the claim that most of the behavioral phenomena of interest to psychologists (e.g., cognition, perception, language, emotion) are instantiated by the process of neural plasticity. When development is viewed in this manner, the fallaciousness of the long-standing and often contentious debate over nature versus nurture becomes apparent. Moreover, by utilizing theneuroscientific tools used to examine the effects of experience on brain and behavioral development (e.g., functional neuroimaging), we may improve how we conceptualize our notions of intervention, competence, and resilience.

Toward a Unified Framework for the Study of Between-Person and Within-Person Structures: Building a Bridge Between Two Research Paradigms

The vast majority of empirical research in the behavioral sciences is based on the analysis of between-person variation. In contrast, much of applied psychology is concerned with the analysis of variation within individuals. Furthermore, the mechanisms specified by psychological theories generally operate within, rather than across, individuals. This disconnect between research practice, applied demands, and psychological theories constitutes a major threat to the conceptual integrity of the field. Following groundbreaking earlier work, we propose a conceptual framework that distinguishes within-person (WP) and between-person (BP) sources of variation in psychological constructs. By simultaneously considering both sources of variation, it is shown how to identify possible reasons for nonequivalence of BP and WP structures as well as establishing areas of convergence. For this purpose, we first introduce the concept of conditional equivalence as a way to study partial structural equivalence of BP and WP structures in the presence of unconditional nonequivalence. Second, we demonstrate the construction of likelihood planes to explore the causes of structural nonequivalence. Third, we examine 4 common causes for unconditional nonequivalence—autoregression, subgroup differences, linear trends, and cyclic trends—and demonstrate how to account for them. Fourth, we provide an empirical example on BP and WP differences in attentiveness.

成瘾人群的决策障碍：研究范式与神经机制

药物成瘾者和赌博成瘾者常常偏好即刻的奖赏而忽视将来的消极结果。在进行决策任务时, 他们倾向于做出不利的选择, 偏好短时的获益而不顾长期的损失, 这是一种决策障碍的表现。延迟折扣任务(DDT)、爱荷华赌博任务(IGT)和剑桥赌博任务(CGT)是研究决策障碍的三种常用方法和范式, 分别考察成瘾人群的冲动性决策、决策短视和决策时的冒险行为。近十几年来的研究表明, 前额叶皮层(PFC)在人类的决策活动中起重要作用。其中, 腹内侧前额叶(VMPFC)、眶额叶(OFC)、背外侧前额叶(DLPFC)等皮层的功能变化与成瘾人群的决策障碍有密切关系。

计时和计数的相似与差异

计时指判断时距的长短, 计数指辨别刺激呈现数目的多少。研究者发现计时和计数具有相似性, 表现在类似的基本原理, 对时间和数目的记忆都受到时间延迟的影响, 跨通道效应类似, 而且药物对它们的影响一致。模式控制模型认为计时和计数共享同一机制, 量值理论的观点是时间和数目等不同维度具有部分重叠的同一表征形式。计时和计数都激活了前额、顶叶、小脑等区域, 但两者在行为结果和激活的脑区上也有部分差异。计时和计数具有同一表征还是两者独立加工, 只在对比反应阶段存在共同机制仍需要进一步研究。     

Forgivingness: Similarities and Differences Between Buddhists and Christians Living in China

Mourners often rely on faith following loss, but not all find spirituality comforting. Some grievers engage in negative religious coping (NRC), signaled by behaviors and thoughts such as anger toward God or their faith community, feeling spiritually abandoned, or questioning God's power. Our longitudinal study of 46 African American homicide survivors explored the relation of both positive religious coping (PRC) and NRC to complicated grief (CG) and investigated whether religious coping more strongly predicted psychological distress or vice versa. Results indicated that NRC was associated with CG, whereas PRC was substantially unrelated to bereavement outcome. Significantly, CG prospectively predicted high levels of spiritual struggle 6 months later, both in terms of CG and NRC composite scores and at the individual-item level. Clinical implications regarding spiritually sensitive interventions are noted.     

Homicide-Suicides Between Adult Sexual Intimates: An Australian Study

Little research that focuses upon homicide-suicides between adult sexual intimates has been conducted to date. Yet U.S., U.K., and Australian studies on homicide and homicide-suicide show that a disproportionate number of those that kill and subsequently take their own lives are the husbands or estranged sexual intimates of their victims. This paper provides some retrospective data on the historical, demographic, and situational traits of this type of homicide-suicide in Australia by looking at what, if anything, differentiates homicides between adult sexual intimates that include the suicide of the offender from those that do not. A lack of significant variation was apparent in histories of domestic violence, alcohol involvement, and unemployment between those who committed suicide and those who did not. However, if the offender was a male estranged from his partner, born outside of Australia, who used a gun as the weapon and killed more than one victim, or was older with an ailing wife, he was more apt to commit suicide. Using anecdotal case study material, causation or explanatory variables are also discussed. These appeared to cluster either around a theme of old age and ill-health or control and pathological-type of possessiveness. The author concludes that more research focusing on the differentiation between the two groups of offenders is necessary in order to better identify contributory variables and to develop risk elements and information for criminal justice practitioners and other service providers.     

Similarities and Differences Between Younger and Older Suicidal People

More younger people attempt and more older people commit suicide, but the bulk of research and treatment activities, presumably by younger professionals, is devoted to the younger suicidal population. In this paper, both younger and older suicidal patients were compared for age differences, age similarities, and the relationships between generations. Examples are presented of the precipitants and family determinants that were most frequently associated with suicidal behavior, with a discussion of their theoretical and clinical implications. The precipitants were based upon developmental tasks and crises which differ with age, while the family determinants were similar at all ages. Families also played a major role in the origin, outcome, and healing of a suicidal state. To a great extent, the steps leading to a self-destructive episode occurred outside of awareness. The examples illustrated both the typical and the unusual experiences that take place during the treatment of suicidal individuals, often involving the therapist in emotional, dramatic, and moving situations.     

成体干细胞可塑性研究中的若干哲学思考

随着干细胞生物学研究的不断深入,成体干细胞被发现可以分化成组织来源与其无关的其他系统的细胞,即成体干细胞的可塑性.但是最近不断有学者对其提出质疑,认为可塑性可能是与"细胞融合"或成年组织中的"多潜能成年祖细胞"有关.面对可塑性上两种截然相反的观点,我们在热切关注其研究进展的同时,也引发了一连串的哲学思考.     

Gender Related Naming Practices: Similarities and Differences Between People and their Dogs

We compared final written letters and spoken phonemes and syllable length in the names of male (N = 250) and female (N = 197) Golden Retrievers to determine if the same gender-stereotyping trends occurring in humans also appeared in dog names. Names were taken from a website of the most popular Golden Retriever names in English speaking countries. Both male and female dogs had names ending in letters and phonemes characteristic of their respective human male and female counterparts. Female dogs had more syllables in their names than male dogs and a higher percentage of male dogs had one syllable names. We conclude that the similarities between human and dog naming practices reflect a pervasive gendered naming phonology.     

成人期个体心理理论的发展、研究范式与神经机制

成人心理理论的发展有助于个体顺利地进行社会互动,更好地适应社会。个体的心理理论能力会随着个体认知能力的发展以及大脑的发育而呈现出不断发展变化的趋势。研究者采取众多研究范式测量了成人心理理论。在进行心理理论加工时,青春期个体更多的激活了内侧前额叶皮层的后部,而青年期个体更多的激活了右颞上沟。根据研究结果,学者们构建了两成分认知模型、共享回路与中线结构整合模型以及心理理论多层次模型来解释成人心理理论能力。在进一步的研究中,成人心理理论的研究还应开发有效的研究范式来逐步揭示心理理论本身发展的特征、心理理论与外界因素如生活环境的关系以及解读互动心理的特征。
